Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs for hybrid electric vehicles suffer from inadequate electrical energy storage and long charging times, which hinder their commercialization due to insufficient battery performance and structural instability, leading to deflection and vibration issues.
Innovation Solution
A battery pack design featuring vertically or laterally stacked modules with reinforcement plates that connect housing assemblies, providing structural stability and preventing deflection by dispersing load and reducing vibration through strategically placed reinforcement plates and connection members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If battery modules are stacked vertically or laterally to increase electrical energy storage, then the battery capacity and vehicle mileage are improved, but structural instability increases leading to deflection and vibration issues
Solution Approach 1:
The battery pack is divided into multiple battery modules that are stacked vertically or laterally. Each module contains a specific number of secondary batteries arranged in series, allowing the overall battery capacity to be increased through modular stacking while maintaining manageable structural units that can be individually supported
Solution Approach 2:
Reinforcement plates are introduced as intermediary structural elements between the stacked battery modules. These plates couple the housing assemblies of adjacent modules together, providing mechanical support and preventing deflection while allowing the modules to be stacked for increased capacity
2Use of energy by moving object
If multiple secondary batteries are arranged in series to increase voltage and energy storage, then the electrical energy capacity is improved, but the housing assembly becomes more prone to deflection and vibration
Solution Approach 1:
The housing assembly is segmented into multiple sections, each accommodating a specific number of series-connected secondary batteries. This segmentation allows the electrical energy capacity to be increased by adding more modules while each individual module housing maintains adequate strength to prevent deflection
Solution Approach 2:
The housing assembly utilizes composite structural design combining multiple materials with different properties. The housing includes plates and structural elements that provide both electrical insulation and mechanical strength, allowing the assembly to support higher voltage configurations without increased deflection
